Posted on May 29th, 2026 | Filed under Press Releases

Vancouver, British Columbia–(Newsfile Corp. – May 29, 2026) – Miravalles Gold Corp. (CSE: SAND) (OTC Pink: SSRSF) (“Miravalles” or the “Company”), formerly Silver Sands Resources Corp., is pleased to announce the completion of its corporate name change to Miravalles Gold Corp., and provides the following updates on the Fairfield Gold Project acquisition and recent exploration activities.

The Company’s common shares are expected to begin trading under its new name and ticker symbol “MIRA” on the Canadian Securities Exchange at the opening of trading on JUNE 2, 2026. The new CUSIP for the Company’s common shares is 60469J106 and the new ISIN number is CA60469J1066.

The rebranding reflects the Company’s strategic focus on the acquisition and advancement of the Fairfield Gold Project located in the State of Nayarit, Mexico.

“We believe the Fairfield Gold Project aligns well with Miravalles Gold Corp.’s strategic direction,” stated Keith Anderson, Chief Executive Officer of Miravalles Gold Corp. “Fairfield brings together a combination of historical gold and silver results, established underground workings, and existing infrastructure in a district with a strong mining history, making it a meaningful addition to our exploration portfolio. Recent confirmation sampling has been consistent with historical data and has provided additional confidence in our understanding of the mineralized system. The acquisition adds a new area of focus for the Company in Mexico, and we are moving forward with planned technical work to further evaluate and prioritize exploration targets.”

Fairfield Gold Project Acquisition Update

As previously disclosed in the Company’s April 30, 2026 news release, Miravalles entered into a Definitive Agreement dated April 29, 2026 with Fairfields Gold S.A. de C.V. (the “Vendor”), pursuant to which the Company may acquire a 100% interest in the 1,012.73 hectare Fairfield Gold Project.

Under the terms of the agreement, the Company can earn a 100% interest in the project through staged cash payments totaling USD$675,000 and the issuance of 5,150,000 common shares over a four-year period. Each tranche of common shares will be issued at a deemed price per share equal to the last closing price of the Company’s common shares on the Canadian Securities Exchange on the last trading day prior to the date of issuance of each tranche.

To date, the Company has completed the following consideration payments to the Vendor:

USD$15,000 cash payment upon execution of the letter of intent
USD$100,000 cash payment upon execution of the Definitive Agreement
Issuance of 1,000,000 common shares upon execution of the Agreement

In connection with the transaction, the Company also issued 1,050,000 common shares to an arm’s length finder as a finder’s fee.

The remaining consideration payable under the Agreement is as follows:

USD$155,000 and 1,000,000 shares on the third anniversary
USD$170,000 and 1,150,000 shares on the fourth anniversary

Upon completion of all required payments and share issuances, the Fairfield Gold Project will be transferred to a wholly owned Mexican subsidiary of the Company.

High Grade Gold and Silver Results Confirm Historic Potential

During a March 2026 site visit, Tim Henneberry, P.Geo., Director of the Company, conducted a series of check samples from historic mine workings and waste dumps across the Fairfield Gold Project to verify historic results and assess the project’s exploration potential.

A total of seven grab samples were collected, including one underground sample from the Miravalles adit. Six of the seven samples returned gold grades exceeding 1 g/t Au, with values ranging to 7.93 g/t Au, while all seven samples returned silver values ranging from 2.1 g/t Ag to 99.6 g/t Ag.

The Company cautions investors that grab samples are selective in nature and may not represent underlying mineralization across the property.

“The presence of gold and silver mineralization across multiple historic workings is encouraging,” added Mr. Anderson. “These results are consistent with historical data and support the merit of further exploration at Fairfield. The project has not been systematically explored using modern techniques.”

QA/QC

All grab samples were collected by Mr. Henneberry or under his direct supervision. Samples were shipped to ALS Minerals Zacatecas, Mexico for preparation, with pulps subsequently sent to ALS Minerals North Vancouver for analysis using the ME-ICP41 and Au-AA26 analytical methods. Over limit copper assays were analyzed using the OG46 procedure.

The Company relied on ALS Minerals’ internal QA/QC protocols and no material discrepancies were observed.
